1. Description of the system
The Fire Damper System (FDS) allows to feed, monitor and test up to 60 fire dampers. Smoke detectors can be con-
nected and monitored, as well. The system is designed to feed only 24V fire dampers.
The system is composed of:
FDS-M
FDS-S
FDS-P
FDS-R
FDS-RB
FDS-DD
FDS-CD

If the communication
cable is more than 300 m,
a signal repeater, FDS-R,
is required This is also
required if the number of
FDS-S exceeds 30.
